The end of the first connecting pipe 21 away from the tee is connected to the interior of the second liquid storage chamber, and the end of the second connecting pipe 22 away from the tee is connected to the interior of the first liquid storage chamber. A drain pipe 24 is installed on the liquid outlet of the water pump 23, and valves are installed on the first connecting pipe 21, the second connecting pipe 22 and the drain pipe 24 respectively; wherein, when the water in the first liquid storage chamber is being pumped out, the first connecting pipe 21 should be closed by the valve on the first connecting pipe 21, and similarly, when the water in the second liquid storage chamber is being pumped out, the second connecting pipe 22 should be closed by the valve on the second connecting pipe 22.

[0028] The interior of the box 10 is divided into a first liquid storage chamber and a second liquid storage chamber by a partition 12; Figure 1 As shown, Figure 1 The left side of the middle partition 12 is the first liquid storage chamber, and the right side of the partition 12 is the second liquid storage chamber. The oil-water mixture is arranged inside the first chamber, and the separated oil after heating flows into the inside of the second liquid storage chamber.

[0029] A floating electric heater 34 is installed inside the first liquid storage chamber, and a pulling mechanism is provided on the floating electric heater 34. The pulling mechanism is used to assist in pulling the floating electric heater 34. The pulling assembly includes a pull rope 41 fixedly connected to the outer wall of the floating electric heater 34. A through hole is opened on the top wall of the box body 10. The end of the pull rope 41 movably passes through the through hole and extends to the outside of the box body 10. A fixed pulley 42 is rotatably installed on the side wall of the box body 10 (the end of the pull rope 41 changes direction through the fixed pulley so that it extends downward along the side wall of the box body 10). A counterweight 43 is fixedly connected to the end of the pull rope 41 away from the floating electric heater 34; wherein, in order to allow the floating electric heater 34 to float in the raw liquid (after the raw liquid is heated, the separated water sinks to the lower layer, the oil floats up, and the unseparated raw liquid is in the middle position), a counterweight 43 is added here so that the floating electric heater 34 can stay in the raw liquid.

[0030] The floating electric heater 34 includes a mounting bracket 341, a first electric heating tube 342, a terminal of the first electric heating tube 342 connected and passing through the interior of an isolation explosion-proof box 343, and a stainless steel hollow tube float 344 at the lower part of the bracket. The first electric heating tube 342 is detachably mounted on the mounting bracket 341 through a mounting mechanism. A sleeve 32 is fixedly mounted on the inner top wall of the box body 10. One end of the flexible explosion-proof tube 33 is mounted inside the sleeve 32.

[0032] A locking assembly is provided on the arc-shaped bracket 51, and the locking assembly is used to fix the arc-shaped bracket 53. The locking assembly includes a threaded groove 56 opened on the side wall of the arc-shaped bracket 51, and the threaded groove 56 is connected to the inside of the limit groove 52. The inner wall of the threaded groove 56 is threadedly connected with a locking screw 55, and the locking screw 55 is used to lock and fix the arc-shaped bracket 53; wherein, in order to further improve the stability of the first electric heating tube 342, a locking screw 55 is provided here, and by rotating the locking screw 55, the end of the locking screw 55 is pressed against the outer wall of the arc-shaped bracket 53, thereby achieving the fixation of the arc-shaped bracket 53.

[0033] A second electric heating tube 44 is installed inside the second liquid storage chamber, and a second temperature sensor is installed on the second electric heating tube 44; wherein, the second electric heating tube 44 can heat the oil in the second liquid storage chamber to improve the fluidity of the oil, thereby facilitating the extraction of the oil through the water pump 23.

[0034] The controller 31 is installed on the outside of the box 10, and the first electric heating tube 342, the first temperature sensor 35 and the second temperature sensor are electrically connected to the controller 31 respectively; wherein, they are installed on the first electric heating tube 342 and the second electric heating tube 44 respectively. The first temperature sensor 35 and the second temperature sensor can monitor the temperature of the first electric heating tube 342 through the first temperature sensor 35, and the second temperature sensor can monitor the temperature of the second electric heating tube 44, and the first temperature sensor 35 and the second temperature sensor are provided with corresponding temperature threshold ranges. When the temperature of the first electric heating tube 342 or the second electric heating tube 44 is lower than the set threshold range, heating will be started, and when the temperature is higher than the set threshold range, heating will be stopped.

[0035] A liquid level sensor is installed inside the box 10, and the liquid level sensor is electrically connected to the controller 31; wherein, the liquid level sensor is installed inside the box 10, and when the liquid level sensor detects that a certain amount of crude oil mixture is injected into the box 10, an electrical signal is sent to the controller 31, and the controller controls the electric heating tube 342 to start heating.

[0036] In this embodiment, the working principle of the device is as follows: when the crude oil mixture needs to be heated and separated, the crude oil mixture is injected into the first liquid storage chamber through the liquid inlet pipe 11. When the oil is injected into a suitable position, the injection of the crude oil mixture is stopped. At this time, the first electric heating tube 342 can be started to heat the crude oil mixture through the first electric heating tube 342, so that the oil and water in the crude oil mixture are separated;

[0037] After the oil is separated from the crude oil mixture, the oil floats up. At this time, the crude oil mixture is continuously injected into the first liquid storage chamber through the liquid inlet pipe 11, so that the oil separated from the upper layer in the first liquid storage chamber overflows into the second liquid storage chamber.

[0038] When the water in the first liquid storage chamber or the oil in the second liquid storage chamber is stored to a certain amount and needs to be discharged, the liquid in the first liquid storage chamber or the second liquid storage chamber can be pumped out by the water pump 23 and finally discharged through the drain pipe 24;

[0039] By designing the floating electric heater 34 to always remain at the boundary between oil and water, as the oil and water separate, the floating electric heater 34 floats accordingly, thereby improving the efficiency of utilizing the heat of the first electric heating tube 342. Compared with the traditional method of always keeping the heating source at the bottom of the tank, it saves electricity consumption and solves the problems of slow heat transfer of the heating device, easy vaporization of overheated bottom, long heating time and low thermal efficiency.
